>while tcm tries to boost the vitality of the body and let it heal?

"Western" medicine also does that, it's just called eating healthy, exercising, and in some circumstances prescribing vitamins because the deficiencies cannot be corrected for some reason.

The difference is that western medicine needs proof that something is working. TCM could have stuff that works, the issue is that there's too much noise (a lot of things that don't work).
